been used. Single-pinion and dual-pinion fixed-speed gear drives offer a relatively simple design. However, process flexibility and optimization can only be achieved with variable speed drives. Furthermore, mechanical problems and maintenance for gearboxes increase operating cost and reduce availability of ball and SAG mills.
Both the SAG mill and ball mill are each driven by two gear units. Because, on a conventional drive variant, only one engagement per pinion with the girth gear is possible per side, an economic power limit of about 8 MW per drive is in effect. With the DMG2 gear units, Siemens said this limit expands to as much as 12 MW per drive.
The SIMINE Gearless mill drives pump system significantly enhances concentrator productivity by eliminating the reducer gear between motor and pump and all corresponding maintenance. In addition, the cyclone pumps with variable speed can adjust their energy consumption to the optimized flow of pulp, resulting in energy savings of up to 30%.

When mill power is between 18 and 20 MW, which is the current manufacturing limit of ring geared mills [2], either a gearless mill drive (GMD) or a ring geared mill with dual pinion motors can be chosen. Selecting between gearless or ring geared design is mostly dependent on size of the mill and power and speed requirements [3].
